1 To all whom it may concern:

Be it known that I, JOSEPH T. SoHLAoKs, a citizen of the United States, residin at Detroit, in the county of Wayne and tate of Michigan, have invented certain new and useful Improvements in Cellular Radiators and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to Which it appertains to make and use the same. 1

My invention relates to radiators of the type used in automobiles, and more generally in connection with explosive engines, and is particularly directed to the improvement of cellular radiators. Generally stated, the invention consists of the novel construction and combination of parts hereinafter described and defined in the claims. The radiator in its preferred form, is illustrated in the accompanying drawings,

wherein like characters indicate like partsthroughout the several views.

Referring to the drawings:

Figure 1 is a diagrammatic view in front elevation showing a radiator designed in accordance with my invention;

Fig. 2 is a perspective view with some parts broken away and some parts sectioned, showing the cellular structure of the radiator core;

Fig. 3 is a perspective'view showing one of the zigzag water tubes of the radiator;

Figs. 4 and 5 are perspective views showing intermediate cell forming plates of the radiator core;

Fig. 6 is a horizontal section taken approxlmately'on the line w as on Fig. 2; some parts being broken away;

Fig. 7 is a view partly in front elevation andpartly in vertical section showing two of the zigzag water tubes and two interlnto zigzag form and certain of which are adapted to be assembled in parallel to form zigzag water tubes, and certain others of which are located intermediate of the water tubes and cooperate with the plates of the water tubes and with each other to afford horizontal air cells or passages opening at the front and rear ends. The zigzag tube forming plates are indicated by the numeral 4, whlle the zigzag intermediate plates are ind cated by the numeral 5. In vertical cross sectlon, the plates4 and 5 follow like zigzag hues, and in the preferred construction they are successively bent to form the three sides of hexagonal cells. The tube forming plates 4, at their front and rear edges are offset at 4*, so that they are brought closely together, and these joints are connected by solder so that the tubes are closed at front andrear, but are left open at top and bottom for communication with slots 6 in the bottom plate of the upper water chamber 2, and'with like slots, not shown, in the top plate of the lower Water chamber 3. In the preferred arrangement of this radiator, two

intermediate plates 5 are placed between each pair of adjacent zigzag Water tubes, and each intermediate plate 5 has a flat sur face 5 that has an extended flat contact with a corresponding flat vertical portion 4 of the adjacent plate 4 of the adjacent water tube. This extended contact insures good conduction of heat from the plates of the Water tube into the intermediate plates, so that the said intermediate plates afford highly eflicient radiating surfaces for the water tubes. It should be further'noted that the said surfaces 5", at their ends, are offset, as indicated at 5*, so as to closely enage the offset edge portions 4 of the tube orming plates The two intermediate plates 5 also have flat vertically extended co-engaging surfaces 5. The intermediate plates 5, therefore, cooperate with each other and with the adjacent tube forming plates 4, to afford hexagonal horizontally extended air cells or passages that are open both at front and rear ends.

The proper alinement of the plates 4 and 5 to form the hexagonal cells, as above de; scribed, is insured by providing the inter mediate plates 5 with reversely bulged alining portions 7, certain of'which fit the reentrant bends or angles of the adjacent .cate or difficult manner.

in Figs. 4, 5, 7 and 8, by reference to Which it will be noted that the said reversely bent portions 7 are simply pressed from the sheet in a direction reverse to the direction of the main portion of the angular channel from which it is partly cut and laterally pressed. These alining portions 7, therefore, so closely fit the walls of the reentrant bends of the plates which they engage, that they almost disappear from view, but nevertheless, afford simple and elficient means for accurately directing the assembling of the plates, and, in the completed structure, very greatly increase the conducting contact between connected plates. They add practically nothing to the cost of forming the plates and do not obstruct the free passage through the air cells.

To provide for vertical circulation of air between the air cells as well as horizontal circulation of air therethrough, the noneontacting portions of the intermediate plates 5 are formed with perforatlons 8.

When the parts of the radiator core are assembled, as above described, all of the contacting portions at the front and rear edges of the plates are connected by solder, preferably accomplished by dipping the edges of the plates into molten solder. In this radiator the number of joints which must necessarily be soldered liquid tight, is reduced to a minimum, and a maximum number of air cells is obtained, with the resulting greatest possible radiating and water cooling efficiency. The accurate assemblage of the cooperating elements is made an easy matter, and the completed radiator core is not only comparatively strong, but has the very much desired hexagonal or honeycomb cell appearance. The metallic plates or ribbons from which the cellular core is made are of the simplest possible construction capable of being very easily pressed to form and not requiring plaiting' or folding of the metal back upon itself in an intri- Furthermore, the interchangeable construction of the zigzag plates or ribbons permits of variation in the manner of assembling, so that one, two, three or more intermediate or radiating plates may be assembled between adjacent laterally spaced zigzag water tubes.

Also, the said construction, above described, permits the water tubes to be directly connected together, without intermediate radiating plates, when such con- I struction is desired.

2. A cellular radiator made up of alternately'bent zigzag plates, certain of which are united in parallel to form laterally spaced water tubes, and certain others of which are assembled between said water tubes and cooperate with the adjacent plates thereof to form air cells, and are provided with reversely bent alining portions that fit the reentrant bends of the adjacent tube forming plates.

3. A cellular radiator made up of alternately bent zigzag plates, certain of which are united in parallel to form laterally spaced water tubes, and certain others of which are assembled between each pair of the said tubes and cooperate with the adjacent plates thereof and with each other to form air cells, the said intermediate plates having reversely bent alining portions that fit the reetrant bends of adjacent plates.

A cellular radiator made up of sheet metal plates successively bent to form the three sides of hexagonal cells, certain of the said plates being connected in parallel to form laterally spaced zigzag water tubes, and certain others of the said plates being assembled between said water tubes and cooperating with the adjacent plates thereof to form hexagonal air cells, the said intermediate plates having reversely bent alining portions fitting the reentrant angles of said tube forming plates.

5. A cellular radiator made up of sheet metal plates successively bent to form the three sides of hexagonal cells, certain of the said plates being connected in parallel to form laterally spaced zigzag water tubes, and certain others of the said plates being assembled between said water tubes and cooperating with the adjacent plates thereof to form hexagonal air cells, the said intermediate plates having reversely bent alining portions fitting therentrant angles of said tube forming plates, the said parallel tube forming plates having their edges off-set and directly united.
